Don't get me wrong - I also think the Federal Reserve has sort of painted itself into a corner with QE. But the way you talk about "the economy will fail again as soon as it's reduced" makes me wonder. In your opinion, what would actually make the economy healthy again, rather than just "propped up"?
What would 'fix' the economy?
Having a lot less govt debt....getting a large volume of people back to work at productive jobs, buying houses they can afford, buying cars they can afford...living financially sustainable lives once again with low debt and high level of savings.
A stock market that isn't overblown and on the verge of a meltdown.
The real problem is that we have a huge population that is out of work and broke, and another tiny population that is barely hanging in there, and a third 0.01% population that is getting so rich off the backs of the previous two that it isn't funny.
We also have a manufacturing sector with zero fiduciary responsibility to their employee's or local communities, enslaving the populations of even weaker economies in order to sell to anyone left that can afford it more cheap crap we don't need. CFO's that will destroy a local economy for the sake of 'their responsibility to the shareholders'...when they don't realize the people who's jobs they just eliminated were the shareholders.
There is also a looming problem of a young and upcoming generation that is refusing to participate in the debt culture that was created by all the previous generations. They can't get anything but service based jobs, paid so low they can't buy anything so they are just saying fuckit....I'm not buying into your bullshit American debt based dream.
I could fill a children's book with what I think is wrong with the economy and it wouldn't matter...there is nothing left to do but watch it burn to the ground and start over again.
No one could fix this economy, it was doomed to fail when it began. Just as it did several times in the past few centuries.
